I have been out of the loop for a bit dealing with family medical stuff (my 2.5 year old had surgery) and work, but should post more in the coming months.
Who makes the claim on the higher vacuum stuff? You got a Brimar 5R4GY with D/box getters? Good stuff. That Haltron double mica comes in about 10-12 different brand names. I have also seen one version of it as a 5R4GYB. I like that tube a lot and it usually trades in the $50 or below category.
I do like the TAK 300Bs. I bought a used pair a year or so ago. They have a great, deep sound. I have another tube or two I am trying to decide on after making adapters. More to come on that. I will say that I don't get into many new tubes, but the Taks are really awesome.

My friend, an audio and video importer, forced me to use power conditioner Furman IT-Reference 20i. Have you guys tried using power conditioner for audio system? My past experience with power conditioner, it killed the life of the music. Everything became so smooth and unreal. The violin sounded like liquid, I can't hear the bow vibrating the strings. So, I am pretty skeptical until now.
My friend demonstrated the electrical noise and this Furman, silenced it. But I am not sure if..this would serve a good point for audio. For video, I have no doubt it will positively benefit the picture quality though.
